Abstract
A longitudinal connection is formed for wooden components and a corresponding wooden component. A fitting piece is glued in a recess to the outer or bottom sides of the at least two glued laminated girders to be connected in such a way that a scarf joint is created at least in a partial length of the fitting piece between the fitting piece and the respective glued laminated girder originating from the tapered and transition regions of the fitting piece in the direction of the end of the associated glued laminated girder.
Claims30
Load-bearing wooden component comprising:
- at least two glued-laminated girders joined together end-to-end with a partial-thickness dovetail joint,
- each of the at least two joined together glued-laminated girders having a respective separate recess on at least one side, the respective separate recesses together forming a common recess,
- a fitting piece provided in the common recess and positively connected to each of the at least two glued-laminated girders,
- the at least two glued-laminated girders being bonded with the fitting piece on their at least one side in the region of the provided common recess by a scarf joint, the scarf joint extending at an angle of inclination (a) at least in a partial length of the fitting piece starting from a merging and transition region of the fitting piece in the direction of an end of the associated glued-laminated girder, and
- a lamella firmly adhesively bonded to at least one of the fitting piece and the glued-laminated girders adjacent to the common recess, the lamella providing strength against both bending and tensile stresses to the component, the lamella comprising a hybrid board lamella formed of a plurality of parallelly glued-together members, wherein the at least two glued-laminated girders have widths and the plurality of glued-together members are arranged adjacently parallel to one another across the widths of the girders such that the plurality of parallelly glued-together members arranged side-by-side span the girder widths.

Load-bearing wooden component comprising:
- first and second glued-laminated girders joined together end-to-end with a partial-thickness dovetail joint, the first glued-laminated girder having an outer surface having a first recess defined therein, the second glued-laminated girder having an outer surface having a second recess defined therein, the first and second recesses of the first and second joined-together glued-laminated girders together forming a common recess;
- a fitting piece disposed in the common recess formed by the first and second recesses, the fitting piece positively connected and bonded by a scarf joint to the first and second glued-laminated girders, the scarf joint extending at an angle of inclination (a) at least in a partial length of the fitting piece starting from a merging and transition region of the fitting piece in the direction of an end of the first glued-laminated girder, and
- a lamella firmly adhesively bonded to at least one of the fitting piece and/of the glued-laminated girders adjacent to the common recess, the lamella providing strength against both bending and tensile stresses to the component, the lamella comprising a hybrid board lamella formed of a plurality of parallelly-glued together wood members.
